Depends on whether a frame shop can straighten it.
Yes, it could may mean the car is not safe to drive, have it checked/repaired by a good garage.
A auto body repair shop with a frame machine can repair the frame.
Contact a good autobody shop that has a frame machine and have them look at it and give you their opinion.
No, if properly repaired it is just as safe as new.
No, if you get into another accident the frame will collapse further, and could cause damage to the occupants. Driving a vehicle with a bent frame is also harder to steer because it interferes with your alignment in most cases.
Provided it has been done properly and is still legal and road worthy
I would take it back to the person who sold it to me or make him come and pick it up and give you the money back.
Regardless of what any tv show or anything tells you a bent frame can be fixed as long as it is not totalled. The car will still work the same and be just as safe.
The cost of a bent frame really depends on the amount it is bent and the location. The price range varies.
I ha a bent frame on my 95 from hurricane damage they put it on a frame puller and its as good as new.
How can you bend the frame without cosmetic damage? Did you run over something? Depending on your insurance coverages, if a vehicle has a bent frame and is no longer safe to drive, then an insurance compamy would usually total out a vehicle. Otherwise, they can pay to repair the vehicle.
